IMPROVEMENT IN BOLTS FOR DOORS OF JAIL-CELLS.

Specification forming part of Letters Patent No. 155,105, datedSeptember 15, 1874; application filed August 1, 1874.

.To all whom it may concern Be it known that 1, PETER J. PAuLY, of St.Louis, St. Louis county, Missouri, have invented a certain Improvementin Looks for Doors of J ail-(Dells, of which the following is aspecification:

My invention consists in attaching the sliding bolts that look thecell-door to a lever, by which said bolts are operated, and the leversof a number of doors in a row are connected to a single sliding baroperated by a lever outside the corridor and inclosed within a lockedcase, so that the lever can only be operated (to lock or unlock thecell-doors) when the case-door is open. The operating-lever, when thecell-doors are locked, engages over a staple to receive a padlock.

In the drawings, Figure 1 is a front view. Fig. 2 is a plan.

A is the corridor, inclosed by gratingB upon the outer side, and thecell-wall G on the inner side. D are the cell-doors, hinged at E, andhaving a hasp-bar, F, by which each door can be secured singly. g g arebolts, sliding in cleats H, and connected to a vertical bar, Gr, havinga link, 9, pivoted to the lower end of a lever, I, which is fulcrumed ati to the wall of the cell, and whose upper end passes through a notch orslot in the horizontal sliding bar J. The barJ extends from end to endof the row of cells. The outer end j of this bar extends outside thecorridor into a locked case, K, and is connected to a lever, L,fulcrumed at l, and whose free end is slotted for the passage of astaple, and is secured by a lock, M. By this lever L the bar J, lever I,and bolts g are moved either to lock or unlock all the cellssimultaneously. 7c is the door of the case K, said door being fittedwith any desired kind of lock. The lever L or look M cannot be tamperedwith as long as the door It remains closed. N is the door of thecorridor, the bolt 0 of which is arranged to slide into the case K,where it is secured by a padlock, P, passing through an eye in the endof the bolt.

It may be arranged, if desired, for the closing of the door to lock thecorridor-door, and to hold it locked until the case-door is againopened. The opening of the case-door in this case would not unlockthecorridordoor, as this would be done by a separate action.

I claim as my invention- The cell-door D, bolts Gr g, cleats H, link 9,and lever I, in combination with sliding bar J, case K, lever L, andlock M, substantially as set forth.

PETER J. PAULY.
